The mallard itself is the ancestor of most domestic ducks, and its naturally evolved wild gene pool gets genetically polluted in turn by the domestic and feral populations. [ 121 ] Over time, a continuum of hybrids ranging between almost typical examples of either species develop; the speciation process is beginning to reverse itself. [ 122 ]
Domestic ducks are mostly promiscuous, where wild mallards are monogamous. Domestic ducks have lost the mallard's territorial behaviour, and are less aggressive than mallards. [7] [8] Despite these differences, domestic ducks frequently mate with wild mallard, producing fully fertile hybrid offspring. [9]
Mulards from crossing with a wild-type mallard (Anas platyrhynchos)The Muscovy is commonly reared for meat. [7]: 78 In commercial production, it is often crossed with a mallard-derived domestic duck such as the Rouen or Pekin to produce the hybrid known as a mulard.
This is a list of the breeds of domestic duck which have official recognition at national or international level. [1] Most breeds of duck derive from the wild mallard, Anas platyrhynchos, while a small minority are descendants of the Muscovy duck, Cairina moschata. Duck breeds are normally officially recognized and described by a national body ...
Farm-raised mallards have changed the DNA of eastern birds. It may quack like a duck, but science shows eastern and western mallards are different Skip to main content
Among species, the survey estimated 146,561 mallards, 8% lower than 2023 and was 18% lower than the long-term mean. Blue-winged teal, the second-most abundant duck in the survey, was estimated at ...
Mallards, both domestic and wild in particular are notorious hybridizers, know to frequently hybridize within the mallard complex and even outside of Anas. The willingness to hybridize has concerned conservationists as the gene flow from the mallard may pollute pure populations of more vulnerable species such as the Mexican duck. [2]
In some regions the name "Barbary duck" is used for domestic and "Muscovy duck" for wild birds; in other places, "Barbary duck" refers specifically to the dressed carcass, while "Muscovy duck" applies to living C. moschata, regardless of whether they are wild or domestic. In general, "Barbary duck" is the usual term for C. moschata in a ...
